Counted from the 117 climbs here that carry a grade. Shown only where there are at least 5 of them — below that the shape is noise.

How well located

Base placed (one source) 2  Position on wall known 115  Crag only 2 

The order of the climbs along this wall is known from the open catalogue, so a few surveys go a long way: standing at Left Crack (a.k.a. Biercrack), Day 0 Starter, East Face (3 climbs, about 90 seconds on Eliminator Boulder) would place up to 20 more climbs between them. Survey the wall →

“Up to” because the estimate between two surveyed routes is only used when they turn out to be close enough together on the ground.

Rock, from the geologic map

Dakota Group. Albian, about 113 to 100 million years old.

Total thickness about 88 m near Ft. Collins, 84 m near Boulder, and 81 m near Milliken. Consists of two formations South Platte Formation?Light- to dark-gray well-sorted fine-grained crossstratified and ripple-laminated sandstone, siltstone, and gray c

This is the map unit under this crag's map point, read from the 1:100,000 sheet (Colton, Roger B., 1976, U.S. Geological Survey Geologic Investigations Series I-855-G). The point can be a few hundred metres from the rock, a cliff often stands on the line between two units, and at that scale a line on the map is about 100 m wide on the ground, so the wall itself may be the neighbouring unit. The rock named at the top of this page comes from the public geology of this area; this card is the map's answer. Every crag on this unit: Dakota Group. Geology data: Macrostrat (CC BY 4.0), serving USGS and Colorado Geological Survey maps.

Photographs near this crag

Taken within 1.5 km of this crag's map point and published under a licence that lets us show them, from Wikimedia Commons. The coordinates say where the camera was, not what it was pointed at, so some of these will be the creek or the trail rather than the rock.

Photos from climbers

No photos here yet. If you're at the crag, yours would be the first.

Pick a photo from your camera roll rather than taking one here: a picture taken inside a browser usually has no location saved in it, and we check that the photo was taken at this crag before publishing it. Photos of guidebook pages and topos are refused — they're the author's work. By sending one you're letting us publish it.

Nobody reviews these before they appear, so anyone can report one and it's hidden straight away — including you, if you change your mind, and including a photographer who finds their own picture here.

Taken at the crag by climbers and published as they sent them. Each one's own location had to be within 0.5 km of this crag before we accepted it. See something that shouldn't be here? Use Report this photo under it and it's hidden at once. Anything else, write to us.

Access & safety

Emergency: call 911. Read out your location: Works without signal. If GPS fails, this crag's approximate map point is 40.56600 N, 105.15560 W (Rotary Park). That point can be off by hundreds of metres, so say so.

The map point for this crag is on land managed by Larimer County (local government), in Horsetooth Reservoir.

The boundary is close. Land managed by City of Fort Collins comes within 250 m of this point, and the point is not the rock — the wall itself may be on the other side of the line. Check which before you rely on either one's rules.

Land manager from USGS PAD-US (public domain), read 2026-09-29. It is the manager of the crag's map point, which can be a long way from the wall. What you may do on the rock is the manager's to say, not ours.

Nobody has yet read Larimer County's own rules for this crag and written them down here, so treat the above as where you are, not as what you may do.

Distances are a straight line from this crag's map point, which can itself be hundreds of metres off; a road may be much longer. Mapped by OpenStreetMap contributors (ODbL), so a toilet missing here may simply be unmapped. Parking here is what OSM has drawn nearby, not a guidebook's directions.
